Title: Centrifugal type brake device
Inventor: KATSUMOTO KIICHI
IPC: F16D51/12
Filed: 1993-03-03
Abstract: PURPOSE:To provide a centrifugal type brake device capable of braking a bearing or the like or transmitting power speedily and uniformly in rising of rotation irrespective of the rotating direction of the bearing or the like. CONSTITUTION:Two sets of brake shoes 6, 7 and linings 8, 9 disposed in a bearing 4 and a boss 5 which are turned around the center of a brake drum 2 are energized by coil springs 12 in such a manner as to be separated from the inner circumferential surface 3 of the brake drum 2 and approach each other. When a rotating speed of the bearing 4 or the like reaches a predetermined value, the linings 8, 9 are oscillated toward the inner circumferential surface 3 by centrifugal force, to be frictionally engaged with the inner circumferential surface 3 in a slidable fashion. Since the linings 8, 9 and the inner circumferential surface 3 are brought into a so-called projected state, relatively numerous portions at the tip in the rotating direction of the linings 8, 9 where large torque is applied to the bearing 4 or the like exist by the number of all the linings 8, 9. Consequently, it is possible to brake the bearing 4 or the like in rising of rotation to a predetermined rotating speed by the relatively large torque.

Title: Abrasion-resistant synthetic resin composition
Inventor: TANAKA MITSURU
IPC: C08K3/00
Filed: 1979-04-09
Abstract: PURPOSE: A synthetic resin composition which provides synthetic resins having improved abrasion resistance and being useful for the production of structural parts, prepared by adding carbon black which has been heat-treated at a specific temperature to a synthetic resin.  
     CONSTITUTION: To 100pts.wt. of a synthetic resin is added 5W20pts.wt. of carbon black which has been heat-treated at a temperature of 2,500°C or higher. With respect to the amount of carbon black added to the resin composition, smaller amounts have a lower effect on abrasion resistance, whereas too large amounts give rise to a plateau of abrasion resistance. Therefore, the amount of carbon black added is 5W10pts.wt. per 100pts.wt. of the synthetic resin. The heat-treatment of carbon black is carried out by heating carbon black at a temperature of 2,500°C or higher, pref., 2,700W3,000°C for 0.5W5.0hrs in an oxygen-free atmosphere, e.g., in an N 2  stream, in vacuum or in an atmosphere of carbon powder.

Inventor: MARUYAMA TAKAHISA
IPC: H02P25/098
Filed: 1987-02-27
Abstract: PURPOSE:To reduce the pulsation of driving current from an actuator by outputting a higher speed out of a current objective speed corresponding to the number of residual tracks from the current detecting track up to an objective track and a small section objective speed calculated from the preceding objective speed on the track just before the current track and a correcting speed found out from the acceleration or the like of a servo head as an objective speed. CONSTITUTION:When a servo head 2 is moved to a position where the number of residual tracks up to the objective track is (n-1), the current objective speed becomes Vn-1, the number of residual tracks in the preceding track is (n) and its speed is Vn. Then the current objective speed Vn-1 corresponding to the number of current residual tracks is found out from a previously stored table and the initial small section objective speed Vn-1 (1) at the number (n-1) of residual tracks is calculated by the shown equation (1). In the equation, alpha is the acceleration of the servo head 2 in moving. The speed Vn-1 (1) is compared with the speed Vn-1, and when the former is larger, the Vn-1 (1) is outputted from an MPU 3A, and when the former is smaller, the Vn-1 is outputted from the MPU 3A.

Title: Iluminating device
Inventor: ISHIMURA SHUNICHI
IPC: G02B6/00
Filed: 1995-02-09
Abstract: PURPOSE: To prevent the occurrence of the unevenness of luminance and the variable density of light caused by the ruggedness of a reflection surface and to enhance the average luminance in the back iluminating of a liquid crystal display panel. CONSTITUTION: The light from light sources 14 and 15 is reflected by the reflection surface 13a of a light transmission body 13, passes through a diffusing sheet 12 from an emission surface 13b, and is given to the liquid crystal display panel 11. The reflection surface 13a comes close to a display part B in the center part A. A recessed surface 13r is formed on the emission surface 13b of the body 13 so as to provide a gap between the diffusing sheet 12 and the surface 13r. In the case the reflection surface 13a comes extremely close to the display part B in the center part A, the luminance in the center part becomes high, but the luminance is prevented from being locally increased in the center part because the reflected light in the center part A is diffused by the space on the recesed surface 13r. Then, the variable density of the light caused by the ruggedness of the reflection surface 13a in the center part becomes inconspicuous. Since the reflection surface 13a is made to come close to the display part B in the center part A, the entire lighting luminance is enhanced.
